Abstract
The utility model discloses a multimode feeding horn and a reflecting-surface antenna, wherein, the front end of the multimode feeding horn is shaped like a horn mouth, the outer edge of the front end port is provided with a throttle groove, the throttle groove is arranged along the outer edge of the front end port of the multimode feeding horn in the form of ring, and the opening direction of the throttle groove is the same with the opening direction of the multimode feeding horn, and the depth of the throttle groove is a quarter of the working wave length. Therefore, the band width of the multimode horn is increased from five percent to seven percent, thereby enlarging the application area of the multimode horn.
Description
Technical field
The utility model relates to a kind of communication antenna technology, relates in particular to a kind of feed horn and reflector antenna of spread bandwidth.
Background technology
It is its feed that reflector antenna all needs an electromagnetic horn.At present, the multimode horn of TE11 mould+TM11 mould is widely used in the feed horn of reflector antenna, and the performance of feed horn directly has influence on the performance of entire emission surface antenna.
The intrinsic working band of multimode feed loudspeaker of the prior art is narrower, and its bandwidth of operation only has 5%, has limited its many application.
Summary of the invention
The purpose of this utility model provides a kind of multimode feed loudspeaker and reflector antenna of working band broad.
The purpose of this utility model is achieved through the following technical solutions:
Multimode feed loudspeaker of the present utility model, its front end are bell mouth shape, and the outer rim of the front port of described multimode feed loudspeaker is provided with choke groove.
Reflector antenna of the present utility model comprises interarea, secondary face, and described interarea is the parabola of axial displacement, and above-mentioned multimode feed loudspeaker are equipped with at place, described paraboloidal summit.
The technical scheme that provides by above-mentioned the utility model as can be seen, feed horn described in the utility model and reflector antenna because the outer rim of the front port of multimode feed loudspeaker is provided with choke groove, have increased the bandwidth of operation of multimode feed loudspeaker.
Description of drawings
Fig. 1 is the structural representation of the utility model multimode feed loudspeaker;
Fig. 2 is the structural representation of the utility model reflector antenna.
Embodiment
Multimode feed loudspeaker of the present utility model, its preferable embodiment as shown in Figure 1, the front end of described multimode feed loudspeaker 1 is a bell mouth shape, the outer rim of the front port of described multimode feed loudspeaker 1 is provided with choke groove 2.
Described choke groove 2 is provided with along the outer rim annular of the front port of multimode feed loudspeaker 1, and the opening direction of choke groove 2 is identical with the opening direction of described multimode feed loudspeaker 1.
The degree of depth of described choke groove 2 is 1/4 operation wavelength.Described operation wavelength is the operation wavelength at the sideband place of the frequency band of need expansion.
Reflector antenna of the present utility model comprises interarea 3, secondary face 4 as shown in Figure 2, and described interarea 3 is the parabola of axial displacement, and place, described paraboloidal summit loads onto the multimode feed loudspeaker of stating 1.
The utility model is by an additional choke groove around the radiation actinal surface of original multimode horn, kept all advantages of multimode horn but makes the bandwidth of multimode horn wide to 7% from 5% expansion, thereby promoted the application of multimode horn.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.
Claims (5)
